Role of the chromatin context in CENP-A deposition. (a) Histone H3 nucleosomes are interspersed within and surround CENP-A containing chromatin throughout the cell cycle (steady-state). H3 nucleosomes within CENP-A containing chromatin are enriched for H3 Lys4 and Lys36 dimethylation, and H3 Lys9 dimethylation marks are found in nucleosomes flanking centromeres. (b) During G1-phase, recruitment of the KAT7 acetyltransferase complex by the Mis18 complex facilitates histone H3 removal and the assembly of new CENP-A nucleosomes.
